APPARATUS FOR STEAM-GENERATING AND'SOLUTION-HEATING PURPOSES.

Application filed March30, 1923. Serial No. 628,842.

To all whomc't may concern:

Be it known that I, OscAn ANTON BRUN- LER, a citizen of the German Republic, residing at 140 West Graham Street, Glasgow, Scotland, North Britain, have invented certain new and useful Improvements in Apparatus for Steam-Generating and Solution-Heating Purposes, of-which the following is a specification such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for generating steam or heating chemical solutions and is of that kind in which a burner is so positioned in relation to water or other fluid that the flame from the burner is immersed in the fluid.

The invention consists more particularly in improved means for igniting the burner and in the construction of the burner.

I will describe the invention more particularly as a steam generator but it must i be understood that the apparatus can be employed for heating chemical solutions and other liquids.

According to the invention I construct the burner so that when the apparatus is to be started a bypass to the burner is first heated by a 1am -or -equivalent, say a blow lamp, and a. or, this bypass or auxiliary burner is sufficiently hot the fuel is turned on to it and will heat up the main burner and ignite the fuel therein when it is turned on to the main burner, said main burner being preferably water cooled as hereinafter described.

Two forms of the invention are illustrated in-the accompanying drawings in which 1 shows substantially the whole apparatus in,one form with the generator outside the storage tank for the steam and water supply. v

Fig. 2 shows a detail of the burner and is substantially a section on line 2-2 of Fig. 1.

Fig. 3 shows another form of the apparatus with the generator inside the steam holder. r

In Fig. 1 aholder or container 1 is adapted to receive the steam from pipe 2, having valve 3,; in its upper part whilst the lower part serves as a storage tank .to' suppl hot water through pipe 4 with valve 5 to t e burner, the sai water coming from any suitable source through the pipe 6. All these parts are of substantially known form.

Adjacent to the container 1 is the generator which comprises aboiler a in which is 60 fitted burner b supplied with any suitable fuel from pipe 0 said boiler havinga draining or cleaning hole at d.

On the upper side of the boiler a is a tube-like part e provided with a removable metal cover f under which is a fireclay or equivalent lining cap. Within the part c is a fireclay or other suitable tube 9 directeddownwardly towards the central portion h of the burner b and leading to passages j which have a common outlet forming the burner proper. A hole 71 is formed through the part it, see Fig. 2 and is 'open to the water in the generator. The passages j are shown of flat form in Fig. 2 but any suit- 75 able shape may be employed.

A fuel bypass tube 0' leads from the tube a to the inside of the part 6. In practice I proceed substantially as follows when starting the apparatus. With the fuel cocks turned ofi I remove cover f and the cap under same and introduce the flame of a lamp into the part'e so as to heat the tube g to redheat. The cap and cover are then replaced and the cock in pipe 0 opened thus admitting fuel (fuel and air) to the tube which combustible mixture ignites, or this ignition may take place before the cap and cover are replaced but when these are in position the flame at g is forced down into the burner b and heats the bridge or part b. This burner may be of cast steel and the part it gets so hot after a. few minutes that upon opening the cock in pipe 0 the fuel and air passing into the burner 9 ignite, and the flame passes at its highest temperature through the outlet in. When this hasv taken place-the admission of fuel and air to the i ition lam may be reduced or shut o The air 1s forced into the ignition lamp and the burner at a higher pressure than the steam pressure, by means of a compressor, (not shown), and thefuel is admitted at a higher pressure than the steam pressure, through the use of any suitable means- When the main flame burns, water is supplied tothe gen-. erator "from the container. The feedwater is pumped into the container. p

The apparatus work with very little,

' if an ,-attentionfor a long period providing t e fuel and water supplies are maintained.

It will be understood that as steam mixed with combustion gases passes out of the generator b ,the pipe 2, water enters the generator t rough pipe 4. The presence of ;team in the container brings the water to a temperature" near boiling point and it is forced close to the flame thus insuring complete combustion.

In Fig. 3 the burner 'm, is immersed in water in" the boiler n which is positioned within the steam container or tank 0. Openings pare provided for the steam above the level of the water in the boiler said water.

, as may be required.

What I cla m is s 1. A liquid heater comprising a casing open to'a liquid supply and having an outlet, a burner arranged in the casing below the outlet, said burner comprising a jacket having a flame orifice in its lower portion and a direct fuel inlet in its upper portion,

and a central part spaced from the jacket part, an

by fuel (passages surrounding such central an lgnition tube arranged at an angle to the jacket and directing the flame therefrom upon the central part. of the burner to heat the latter.

2. 'A liquid heater comprisinga casing open to a liquid supply and having an outlet, a burner arranged in the casing below the outlet, said burner comprising a jacket having a flame orifice in its lower. portion and a direct fuel inlet in its upper portion, a central part spaced from the jacket by fuel passages surrounding such central part,

an ignition tube arranged at an angle to the jacket and directing the flame therefrom upon the central part of the burner to heat the latter, a fuel pipe leading to the fuel inlet of the burner, and a bypass leading from the fuel pipe to'the igniter tube.

3, A liquid heater comprising a casing open to a liquid supply and having an outlet, a burner'arranged in the casing below having a flame orifice in its lower portion and a' direct fuel inlet in its upper portion, and a central part spaced from the jacket by fuel passages surrounding such central part, and an ignition tube arranged at an angle to the jacket and directing the flame therefrom-upon the central partof the burner to heat the latter, the central portion of the burner being formed with an opening extending entirely therefrom and open to the casing at the ends of the burner.
